Due to the space of the capacitors, specially small size capacitors, sometimes manufacturers use code letter to save room of the marking.
Today, we would like to introduce the EIA/IEC/JIS Common Tolerance Codes about capacitors.
There are lots of code under this system, however J, K, M used most often.
Also, we should not follow the code table exactly, as some factories will have some change on their own.
Such as, WEE Technology use I for ±3%, some use H or E.
So, when you order some capacitors, you have to write down the not only the tolerance code, but also the numbers of each tolerance.
| EIA/IEC/JIS Common Tolerance Codes | |||
| Range | Usage | Letter | Tolerance |
| <10pF | rare | A | ±0.05pF |
| <10pF | B | ±0.1pF | |
| <10pF | C | ±0.25pF | |
| <10pF | D | ±0.5pF | |
| 10pF & up | rare | E | ±0.5% |
| 10pF & up | F | ±1% | |
| 10pF & up | G | ±2% | |
